Criminal justice client rehabs are available as being a far better option than jail time or heavy fines for many who have been convicted of any sort of drug or alcohol related crime. For instance, someone who has been in prison for driving under the influence of alcohol or drugs may qualify to receive rehabilitation services for his or her problem rather than serving time in jail. The judge might even order that the individual receive treatment, either alone or in addition to other sentencing. First-time offenders in particular tend to be given the opportunity to choose a criminal justice client rehab as an alternative to other sentencing, and it is highly recommended they benefit from it when it is a choice. The theory behind criminal justice client rehabs is that it is much more effective and efficient to invest time and effort into rehab than punishment. Much research has been completed to discover how effective this strategy is on recidivism rates, i.e. if the criminal justice client returns or not to criminal justice system following treatment. The signs and indicators appear to be quite positive, and criminal justice clients who do experience treatment have a much better probability of remaining out of the judicial system after rehab.
